Everything about Magnetic Susceptibility totally explained

In electromagnetism the magnetic susceptibility (latin: susceptibilis “receptiveness”) is the degree of magnetization of a material in response to an applied magnetic field.

Definition of volume susceptibility

» :See also Relative permeability.

The volume magnetic susceptibility, represented by the symbol chi_ (volume susc.)

Sources of confusion in published data

There are tables of magnetic susceptibility values published on-line that seem to have been uploaded from a substandard source, which itself has probably borrowed heavily from the CRC Handbook of Chemistry and Physics. Some of the data (for example for Al, Bi, and diamond) are apparently in cgs Molar Susceptibility units, whereas that for water is in Mass Susceptibility units (see discussion above). The susceptibility table in the CRC Handbook is known to suffer from similar errors, and even to contain sign errors. Effort should be made to trace the data in such tables to the original sources, and to double-check the proper usage of units. Use them at your own risk!
